Hose-nozzle.

T o all 'whom It may concern.'

Be it known that we, VILLIAM OBRIEN and FREDERICK lV. VVADDELL, citizens ot' the United States, and residing in the city of Pittsburgh` in the county of Allegheny and Stateyof Pennsyl vania. have invented or discovered new and useful Improvements in Hose-Nozzles, of which the following is a specification.

Our invention consists in neu' and useful improvements in hose-nozzles, combining in one device the function of a washer, from which the stream allowed to escape at full pressure, with that of a sprayer.

The nozzle is normally 'and automatically shut oft by the water-pressure and is opened againstthe latter by linger-pressure, the passage of the water through the bore of the nozzle being controlled and regulated by means which move in both a longitudinal and rotary direction.

Novel features of structure 'and arrantgge` ment of parts will appear from the following; description.

lnthe acconip'anyinylr drawings, Figure l is a side elevation of our improved nozzle, the valve portion being broken away in section to show the parts and the plug' being Shown elevated to close or shut. of the nozzle; Fig. 2 is a vertical section alonen the'. line H-ll in Fig. l, the plug being shoivn @depressed to open the nozzle bore to its full extent` and Fig. 3 is a similar view showing the plug but partially depressed to form a spray.

The followingv is a detailed description of the drawings.

A is the nozzle having a longitudinal water iiassage or bore l, a discharge end 2 and a butt 3, the bore of the nozzle at-tho butt being expanded at 4. The diameter of the nozzle adjacent to the bore is en.- larged and provided With a diametric valve seat 5 which is Closed at one end by ineens of a screw-plug 6. The upper end of said seat 5 is contracted circuinfcren-tially by the internal fianfre 7.

` 8 is a valgve plug Fitting in seat 5 and adapted to both reciprocate and rotate therein. Said plug is provided with a diaanetrio port 9 of equal capacity to bore l, and-adapted to register with said-bore when said plug is properly positioned.

The plug 8 is inserted in seat 5 from below and is provided With a reduced stein l() which extends up through the flange 'T and Specification of Letters Patent.

is provided vvith one 0r more spiral grooves '11 which engage pins or projections 12 on the flange 7. thus causing the plug to rotate as it moves longitudinally. giving sad plugl a `spiral motion. The grooves 1l each make but a quarter t'urn around said stein and the pinsl l2 are so placed that when the plug is in its extreme elevated position, as shown in Fin'. l. the port Sl is at rie-lit angles to bore l, and when the plugr is in its extreme depressed position` as shown in Fig. 2, the port 0 registers with said bore 1.

The plug' 8 provided near its upper end with a circinnterential groove I3 in which is seated a gasket or packing 14 of similar material which contacts with the valve seats and prevents the upivard escape of Water.

rThe out-er or upper end of stem 10 is provided with a swiveled cap l5 which does not turn with the plugand stein and which limits the downward movement of the plug, thus at. all times maintainingr a chamber between the lo\\"er end ot the plug and the bottoni of valve seat 5.

A passage 1G leads from the bore 4 to the bottom oi valve seat 5, thereby maintainingwater pressure under the valve plug 8. t

The operatimi ot our device is as follows: Normally the valve plug 8 is maintained in its elevated position. as shown in Fig. l, by the water-pressure beneath said plug, thus closirrg the bore l and entirely preventing the passage of Water along the same. To open the nozzle, the operator presses his linger upon the cap l5, depressing the lplug 8 against the Watenpressure beneath the same. It the plug oe depressed to its lower most position, the port. 9 will exactly register with the bore l through the spiral movement of the plug.` thus" allowing the wat-er to escape through bore 1 at ull pressure. A partial depressionof the plug will result in but. a partial registration of the port* 9 with the bore 1 and result in a spraying effect. The .:haracter of the spray may be nicely regulated by the amount of depression given to the valve plug. A cessation of pressure on the upper end of the stem Will at once result. in the Water-pressure beneath the plug forcing' the saine upward and sluittingpl" the nozzle completely.

lt is evidentI from the above that our nozzie is of especial value for use Wherebut one hand can be given tohandling' the hose, as, t'or instance, in the Washing of vehicles, The

hose may be dropped when not needed, the nozzle at. once automatically closing and preventing the escape of Water until it is picked up and the finger ot the operator applied to the cap on the end of the stem. This. prevents Wastey of water and greatly expedites the work. vThe nozzle is also nonintensive, since the manner'fof closing the renne prevents the sudden rise in pressure in the hose whenv the-nozzle is closed. It is well known that il. a nozzle is suddenly and completely closed, the hose pressure rises immediately for the time being, frequently resulting in the bursting of the hose.

The construction of our device is /very simple and inexpensive; it contains but few parts and these too substantial to quickly wear out or break, no'springs or other unre liable elements being used, and the device may be taken apart oi-,put together in a x'iiomtot. v

1. A hose-nozzleprovided with a longit-udinal bore, alvalve seat open at one end intersecting -said bore, and a passage leading from the I'butt end et said bore into the bottom of said valve seat; a valv plug mounted in said valve seat and provided with a transverse port adapted to register with said bore when said -plug is. pressed down in said seat` and coacting elements on said valve seat whereby said valve plug is capable of a spiral movement.

2. A hose-nozzle provided with a longi- \,tudi1u1l'bn-e, a valve seat open at one end bottom of said valve seat, a valve plug slidably mounted in said valve seat and having ja ltransverse port adapted to register with said bore when 1n vits innermost position, a

protruding stem for said valve plug having a spiral groove, and a pin extending into said valve seat and engaging said groove whereby said valve plug is caused to move spirally.

3. A hose-nozzle provided with a longitudinal bore, a valve seat intersecting said bore and hav'ng one of its ends open and of reduced ldiameter while its other end is closed byka removable plug, a pass ge oon-V nee-ting the butt -end of said bore 1th the closed end of said passage, a valve-plug mounted in said valve seat and capable of sliding longitudinally therein and having a transverse port adapted to re ister with said bore when said plug is at its innermost position, a reduced stem for said plug protruding through the reduced end of said valve seat and 'provided With a spiral groove, and a projection extending from the Wall of said valve seat and engaging said groove, for the purpose described. f l
